GPO loopback mode

Mishra

I think I figured this out by typing it all here and thinking about it more... This is how this works (NO ONE has a diagram like this online... this would make so much more sense)

How GPOs are applied

Normally

OU A (which hosts users) has group policy B applied

GP B has
computer settings
user settings

User settings are only applied

OU B (which hosts computers) has group policy B applied

GP B has
computer settings
user settings

Computer settings are only applied

Loopback processing mode applied REPLACE

OU A (which hosts users) has group policy B applied

GP B has
computer settings
user settings

NO settings are only applied

OU B (which hosts computers) has group policy B applied

GP B has
computer settings
user settings

All settings are applied

Loopback processing mode applied MERGE

OU A (which hosts users) has group policy B applied

GP B has
computer settings
user settings

User settings are only applied FIRST

OU B (which hosts computers) has group policy B applied

GP B has
computer settings
user settings

All settings are applied

That sounds about right.

basically user settings are ignored


Loopback processing mode applied MERGE

The user policy settings applied are the combination of those included in both the machine and user GPOs. Where conflicts exist, the machine GPOs "win".

agree with Mishra

Thats kind of a long way to describe it, and honestly I didn't follow.

Normal Mode:
1. Computer Settings
2. User Settings

Loopback mode:
1. Computer Settings
2. User Settings
3. Computer Settings (From the GPO linked to the user)

In replace mode, the step 2 settings are forgotten. In merge mode, both settings are added together with the computer settings having a higher priority (because they were applied last)

That's how it passes through my brain.
